The Challenge

1. Reoccurrence of Stuttering
2. Discomfort in Identifying symptoms
3. Limitation in Stabilization stage

The Outcome

1. Children can continuously practice through the service at home or center.
2. Children become a broadcasting creator and use video effects which help them enjoy recording.
3. Sharing diverse tasks for stuttering children to accomplish their fluency practice helps children to experience various situations.


The Process

The process

Background

1. Stuttering, also known as stammering, is a speech disorder. More than 70 million people worldwide stutter.

Background2

2. The cause of stuttering is complex and unknown. Linguistic speech disorders are caused by a combination of environmental and psychological factors.


3. The frequency of stuttering is highest between the ages of two and five. Early treatment is therefore necessary.


4. The 20% of children’s stuttering continues even if they became adults. For adults, the fluency can be improved by the therapy.

5. Conventional treatments

The Van Riper’s Stuttering Modification Therapy

The therapy focuses on a goal to speak with ease and not just aiming at fluent speaking.

Fluency Therapy

The main goal is to speak more fluently. - by Neilson & Andrews, Ryan, Webster

Integrated treatment

Combination of The Van Riper’s approach and Fluency therapy.

Desensitization

Person who stutters learns strategies to reduce negative feelings and anxiety associated with stuttering.

Modification

Modifiy the stutter by training activities such as Cancellations, Pull-outs, and Preparatory set techniques.

Stabilization

The person who stutters becomes self-aware and confident in monitoring his/her own stutter behaviors.


Problems

Financial distress

Financial distress

“My daughter have been receiving cognitive and play therapy for two years, and I'm paying almost 10 million won a year, but with a tight income, it's hard to maintain the treatment.”- Ms. M. with a 4-year-old daughter who was diagnosed with a speech disorder by the Department of Neuropsychiatry a year ago.

Psychological distress

Psychological distress

"Among middle and high school students, there are also reports of cases where they are unable to get along with their peers due to stammering and suffer from bullying."

“My stammer forced me to leave the company. After 5 to 6 years of job hunting, I failed to join the company due to stuttering.” - Mr. A(34), who chose to voluntarily quarantine from society due to his lack of confidence by stammering.

High risk of relapse

High risk of relapse

“Other language disorders do not get worse when they are improved, but stuttering is most likely to recur. That's why stuttering is an area where even a speech therapist isn't confident. There are many language therapists, but fewer people who specialize in the stutter.” - Ms. J, language therapist at Severance hospital.


Review Matrix

Review Matrix

From the review matrix, there were fewer services for children and need further assistance from fluency improvement treatment. Also, more participation was required from therapists and counselors since there was a limited number of services.


Interview

Affinity Diagram

Affinity Diagram

Interviewed a speech therapist who graduated from a Ph.D. program in language pathology at Ewha Woman's University. She is currently working as a speech therapist at Severance Hospital. In addition, several speech therapists, as well as Dr. Lee who is dean of the Speech-language therapy and aural rehabilitation department at Woosong University, helped our project.

lighteningTherapists sometimes feel pressure to create a new content for therapy to identify the symptoms.

The problem of stuttering

The problem of stuttering

lighteningOther language disorders do not get worse when they are improved, but stuttering is more likely to recur.

lighteningPatients with severe illness are sent to a professional institution which means the access of treatment is quite hard.

lighteningIt is also necessary to check the secondary behaviors such as scowling.

lighteningEscape behavior - a secondary behavior that patients repeatly do to escape from stutter such as eye blinking, jaw jerking, tapping or more - can get worse. So identifying not only speech disorders but also observing the behaviors of the patients is important.


Problem Statement

During the symptom identification phase, therapist sometimes feel the pressure not to make the children get upset and to create a new therapy activities for symptom identification. Children sometimes don't want to see themselves during the treatment because some treatment method requires children to be filmed to identify their stuttering symptoms.

The therapist takes a video to observe the patient at the stabilization stage to help patients to practice their fluency. However, due to prolonged treatment, children lose their interest in the practice and unaware they are in the process of treatment.


Low-fi | Mid-fi

Our team was able to develop our prototype by getting advice from speech therapists at Shin’s Speech-Language Clinic. The prototype aims to create a service based on play therapy that can be used in the clinic and as well as children's homes.

Because the patients have to do training at home as a part of treatment homework, the service will help them to practice fluency. This can also help patients' parents as they were the ones who helped their children to participate in practice.

Video Camera

Children become content creators

Recently, a content creator such as a YouTuber has become popular and becomes a dream for elementary school students.
Children at the Shin’s Speech-Language Clinic who helped this research are also familiar with YouTube video media and want to broadcast themselves.

Chatting

Practice solving problems close to everyday life

For each child, the therapist can set different goals to help them improve their fluency or set various questions that have been frequently asked in daily life. Then, the therapist will evaluate their patients' fluency and prescribe it.


Usability Testing

Test

The results of the study showed that the Tingling Cast service motivated users to participate in treatment and promoted greater awareness of their stuttering, while also teaching them the skills needed to actively learn to maintain their own speech fluency. Speech therapists highlighted the fact that children showed an observably greater interest in participating actively in their therapy sessions. Based on these findings, the use of Tingling Cast can be beneficial in the treatment of speech fluency for, and the language development of, stuttering children. Subsequent studies will be conducted to offer services that can help reduce the psychological stress experienced by speech therapists in their work.
